HOWEL THOMAS AND CHARLES E. DELINE, OF WATERTOWN, NEW YORK.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed March 22, 1906. Serial No. 307,509.

To all whom it may concern:

Be it'known that we, HowEL THOMAS and CHARLES E. DELINE, citizens of the United States, residing at Watertown, in the county of Jefferson and State of New York, have invented certain new and useful Improvements in Apparatus for Making Artificial Building- Blocks; and we do hereby declare the following to, be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for making blocks of artificial stone, and comprises various details of construction and combinations and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claims.

Our invention is illustrated in the accom panying drawings, in which Figure 1 is a vertical sectional view through the apparatus, showing parts in elevation and illustrating the plunger in its lowest position. Fig. 2 is a similar view showing the plunger raised." Fig. 3 is a perspective view of the apparatus, showing a block which has been formed and in readiness to be removed from the apparatus. Fig. 4 is a View of a slight modification, showing means for varying the size of the mold and Fig. 5 is a detall view of a division-block forming a part of the invention.

. Reference now being had to the details of the drawings by letter, A designates the base of the apparatus, from whichstandards A and A rise, and A is a cross-piece supported by said standards and upon which the moldbox B is mounted. Said box has its top and bottom open and is providedwith a swinging side C, which is hinged to the slotted strip D, forminga portion of one side of the box, said strip having an elongated slot D therein pro vided for a purpose 'which will presently be described. Said swinging side is provided with lugs d, projecting beyond the ends thereof and adapted to be engaged by the pivotal hooks E, which are mounted upon the ends of the box, thereby affording means for holding the swinging side closed. It will be noted that the inner surface of said swinging side is irregular, as at C,

of the follower a screw S is adapted to bear, said screw being mounted in'threaded aperadapted to imitate the rough-hewn surface of a stone to give the same appearance to the block when molded, and the inner face of said swinging side has two transverse slots C which are adapted to receive the tongues B,

which are formed upon the ends of said box, thereby making, when the swinging side is closed, tight joints. The opposite side of the box from that to which the swinging side is pivoted, it will be noted, -is also provided with an elongated slot D.

F designates a plunger which carries a central oblong 'core H upon its upper surface, and said plunger is of a size to fit and move snugly through the mold-box. Each end of said plungeris grooved, as at F, to receive the end guide-pieces G, which project from the inner surfaces of the ends of the moldbox. Said guide-pieces G, which form end cores, are convexed upon their outer faces.

adapted to rest upon the upper surface of the plunger and is provided with an oblong aperture I, conforming to the shape of the core H, which plate is adapted to telescope over said core and rest upon the top of the plunger and forming a bottom for the block tobe molded. N designates a follower having an oblong aperture N therein adapted to receive the core H, and said follower is provided with recesses O atthe ends thereof adapted to receive the end cores of the moldbox. Said follower has a central recess Q running its entire length, and against the top tures in the plates T and the overhanging portion J of the frame of the apparatus, and a cross-bar L, with weighted ends, is fixed to said screw whereby the same may be turned. P designates a lever which is fulcrumed upon a pivot-pin P, mounted upon a cross-piece of the frame of the apparatus, and one end of said lever is widened, as ml, and is positioned underneath said plunger, whereby as the outer end of thelever is tilted said plunger and the block which may have been formed in the box may be raised so that the bottom of the block will be upon a plane coincident with the top of the box.

W W designate two strips which are pivotally connected to the top ofthe'box and are adapted to swing underneath the base-plate I to support the same after a block has been raised by the plunger.

. I designates a plate or board which is Referring to Fig.4 Orthe drawings will be seen the means for regulating the size of the =mold-box, whereby blocks of different sizes may be molded, and in which figure a division-block K isprovided, which is of a width equal to the width of the mold-box and is provided with two lugs K, which are a ertured' to receive a rod K one end of w ich rod is provided with ahead and its opposite end threaded to receive a winged'nut 'K 'ln adjusting'the division-block thelat- -'te'risplaced within the-mold-box in any po- 'sitionintermediate the ends of'the box according-to the size of theblock-wished to be madeyand the rod K is placed through'the -"two slots D,fo'rmed in'the opposite sides of the box, and also through the apertures in the lugs K and said block isheldin an'adjusted position by'tightening the nut upon the rod. lt willbe understood that when blocks of different sizes are to be made'in the mold-box a plunger of corresponding size is utilized to 'raise the' block after the same has been molded.

In"operation,"the bottom plate I being placed'over the central core upon the plunger andthe swinging side closed,-themold-box is filled'with-material to be'molded, after which thefollower is placed over the core and into the top of the-box, and by turning the screw against the follower the latter'may be forced "down, thoroughly compacting the =material within the box, =and "after the composition forming-'theblock has set the hooksE are rethe swinging side is closed and locked and the strips'L,"which are pivoted on the top of the box,areswung around across the top of the box andform a support for the plate I upon which the molded block rests. When adjusting the apparatus to 'm-ake different-sized blocks,'the plunger'K'is adjusted in any'desired position within the mold-box andheld "by means of the thr'eadedrod and nut,'while aplun'ger of a suitable size is utilizedfor raising the block from the mold.

What'we claim'is 1. An apparatus-formaking blocks of arti- *fi'cial stone,comprising a mold-box, a hinged side to said-box adapted to contain a suitable design'for the face of a block, a strip fastened tosaid side and projecting beyond the ends thereof, said side havingtransverse grooves thereln adapted to receive flanges'upon the ends of themold box, pivotal hooks mounted "uponthe' ends of the box and adapted to engage oven-the ends of said strip to hold the side closed, a movable partition within the box, lugs on one side of saidpartition, a screw passing through registering apertures in said lugs and extending through slots in the walls of the box, a plunger mounted within the box, and a pivotal lever adapted to raise the plunger within the box, as setforth.

2. An apparatus for making blocks of artificial stone, comprising a mold-box, a hinged side to said box adapted to contain a suitable design for the face of a block, a strip fastened to saidside and projectingbeyondthe'ends thereof, said sidehaving transverse grooves therein ada ted to receive flangesuponthe ends of the Inold box,-pivotal hooks mounted upon theends of the box and adapted to'engage over the'ends ofsaid strip to hold the and a pivotal lever adapted to raise the plunger within the box, a core projecting from the upper surface of the plunger, a follower,

and a threaded screw-adapted to bearagainst saidfollower; as set forth.

3. An'apparatus'for making blo'cks of artificial stone, comprising amold-box; a-hinged side to said box adaptedto' contain a'suitable design for the face of a-b1ock,-a strip fastened to said side and-projecting beyond the ends thereof, said side having transverse grooves therein adapted to receive flanges upon the ends of the'mold-box, pivot'alhooks mounted upon the ends of the box and adapted to engage over the ends of said stripto holdthe side closed, a movable partition'within the box,"lugs on one side of said-partition, a'screw passing through registering apertures in said lugs and extending through slots'in the walls of the box, a plungermounted within the box,
